Discussion of anti-interference detection method based on CW small signal

摘要

In this paper, four anti-interference detection methods based on a CW small-signal are discussed separately. First the basic principles of various methods about the energy identification, frequency discrimination, SNR identification, pulse width identification are introduced, and then their advantages and disadvantages are analysed. Finally these measures can ensure sensitivity and effectively improve the detection capability of the system. when environment is disturbed by complex electromagnet.
